Rohini Palaniswamy commented on TEZ-3140:
-----------------------------------------
bq. -1 tests included. The patch doesn't appear to include any new or modified
tests.
Just change in serialization logic. Existing tests (For eg: TestMRRJobs)
cover that and they will fail if even if 1 byte is not copied correctly.
> Reduce AM memory usage while serialization
